These extensions require the same version of MSVC as used for the
corresponding version of Python itself. Some extensions require a recent
"Platform SDK" from Microsoft, and in general, the latest service packs
should be installed, but run 'setup.py' without any arguments to see
specific information about dependencies. A vanilla MSVC installation should
be able to build most extensions and list any extensions that could not be
built due to missing libraries - if the build actually fails with your
configuration, please log a bug via http://sourceforge.net/projects/pywin32.
